Check Digit Verification of cas no
The CAS Registry Mumber 170159-62-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,0,1,5 and 9 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 170159-62:
(8*1)+(7*7)+(6*0)+(5*1)+(4*5)+(3*9)+(2*6)+(1*2)=123
123 % 10 = 3
So 170159-62-3 is a valid CAS Registry Number.
